Graphic analysis of osmotic fragility of erythrocytes.
A precise and highly reproducible method for analyzing the osmotic fragility of erythrocytes with a minute amount of blood (less than 10 mul) is described. The osmotic fragility curves are recorded with a coil planet centrifuge with accessories and a scanning photodensitometer. The recorded curves are transcribed by a DuPont Curve Resolver and their components are analyzed. Normal fragility cur...
متن کاملEffect of parathyroid hormone on osmotic fragility of human erythrocytes.
The survival of erythrocytes (RBC) is shortened in uremia, and it has been shown that calcium influx into RBC evoked crenation and increased their rigidity. The high blood levels of parathyroid hormone (PTH) may augment entry of calcium into RBC and hence affect their integrity. We examined the effect of PTH on osmotic fragility of human RBC and investigated the mechanisms through which PTH int...
متن کاملOsmotic Fragility of Human Erythrocytes is Altered by Porphyrin Compounds
The chemical specificity of Porphyrin derivatives, Tetraphenylporphinesulfonate (TPPS), 5, 10, 15, 20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron (III) Chloride (FeTPPS) and 5, 10, 15, 20-Tetrakis (4-sulfonatophenyl) porphyrinato Iron (III) nitrosyl Chloride (FeNOTPPS), on osmotic fragility of erythrocytes was examined in vitro. TPPS increased the osmotic fragility of erythrocytes more effec...
متن کاملOsmotic fragility of erythrocytes in Duchenne muscular dystrophy.
Osmotic fragility of erythrocytes was studied in ten Duchenne dystrophic patients and eight healthy controls. Lysis started in Duchenne crythrocytes at a concentration of 6.5 g/l NaC1 and in the control erythrocytes at a concentration of 5.5 gIl NaCI. At all concentrations of sodium chloride (from 6.5 g/l to 4.5 g/l) significantly greater lysis was observed in the erythrocytes of dystrophic pat...
متن کاملA Study on Osmotic Fragility of Erythrocytes of Tuberculosis Patient’s Blood
The paper presents the data on percent lysis of hemoglobin in Tuberculosis patient’s blood. Osmotic fragility is the ability of RBC’s to resist rupture (lysis) in hypotonic saline. The degree of hemolysis can be estimated by measuring the colour intensity of the supernant in a spectrophotometer at 540nm and comparing it with 100%. The task is to examine the relationship between the extent of he...
